node.js - Learnyounode http collect off 一个

Question

我正在通过 learnyounode 教程学习 node.js，但一直停留在 HTTP-COLLECT 练习中。我想让我的代码在没有第三方程序帮助的情况下工作。它几乎可以正常工作，但由于某种原因，它没有从 learnyounode 从中吸取数据的任何源接收到第一个数据 block ，所以我的代码是错误的。到目前为止，这是我的代码:

http = require("http");
var info = [];

http.get(process.argv[2],function(res){
    res.setEncoding('utf8');
    res.on("data",function(input){
        info.push(input);
    });
    res.on("error",console.error);
    res.on("end",function(){
        console.log(info.join(""));
    });
});

终端输出:

1.    ACTUAL:  "As busy as a fossicker mate built like a bluey. As dry as a sickie piece of piss mad as a beauty. As cunning as a trackies with get a dog up ya muster. Gutful of mate's rate piece of piss lets get some battler."
1.  EXPECTED:  "402"

2.    ACTUAL:  "We're going bottlo also come a holden. Grab us a bradman no dramas he hasn't got a ironman. She'll be right nipper no dramas she'll be right sheila. Mad as a pav also he hasn't got a barbie. "
2.  EXPECTED:  "As busy as a fossicker mate built like a bluey. As dry as a sickie piece of piss mad as a beauty. As cunning as a trackies with get a dog up ya muster. Gutful of mate's rate piece of piss lets get some battler."

3.    ACTUAL:  ""

4.    ACTUAL:

我看到了this在 SO 上发帖，但它并没有真正帮助我，因为 1) 我正在尝试按照练习提示中的说明使用 http.get() 和 2) 我的问题似乎与代理问题无关。任何提示/帮助将不胜感激，我不确定如何从这里修复代码。

Answer 1

D'oh...在仔细研究之后，我发现了问题所在:第一个数字不是我丢失的数据，它只是接收到的文本的字符长度。其实程序本身并没有什么问题。我通过在 console.log(info.join("")); 之前添加 console.log(info.join("").length); 来修复我的代码行。
